Purpose: Humans are the only known natural hosts of hepatitis C virus (HCV). This study was undertaken to examine the frequencies of human leucocyte antigens (HLAs) Class I and Class II genotype profiles in anti-HCV-infected patients of Northern India. Materials and Methods: From a period of January 2013 to August 2014, 148 anti-HCV-positive patients of North India referred to the Department of Molecular Biology and Transplant Immunology, Indraprastha Apollo Hospitals, New Delhi, for performing HLA typing were included in the study. Results: A*02, A*31 allele frequency decreased significantly in anti-HCV-positive patients. Frequencies for HLA-B loci did not reach any statistical significance. Among the Class II alleles, HLA-DRB1*03 and HLA-DRB1*10 were significantly higher in the patient population, and HLA-DRB1*15 was significantly decreased in the patient population as compared to the controls. Conclusion: HLA-A*33 was significantly increased as compared to control population and showed geographic variation in HCV-infected individuals of India.
